In general, all kinds of aircrafts have the flight data storage systems such as DTS, Black-box and etc. Data to be stored in such equipment contains very important information that is related to the flight performance and security. For effective storing of the critical information that is included in the flight data, the compression or encryption is essentially required. In present, the flight data is stored without compression unlike voice data, but the compression and secure processing are needed to the efficient storing and the security of flight data in case of the fighter. In this paper, we propose a real-time data storage system that is composed of the compression of the flight and voice data based on DPCM, the encryption of the compressed data using AES encryption algorithm and the re-arrangement of the encrypted data by shuffling technique. The proposed system is implemented in hardware using Verilog HDL and we tested the performance of the system with the simulation flight and voice data. As a result, we found that the proposed system compress the data efficiently and enhances security characteristics.
